Citigroup, Inc. (NYSE:C) is one of the banks that could now offer a dividend to its stockholders now that any uncertainty surrounding the Basel III agreement has dissipated.

Citigroup, Inc. is one of the companies that is overcapitalized. With so much money on hand

“[The Basel agreement] answers important questions and begins to create needed certainty," said Citigroup Chief Financial Officer John Gerspach in a memo Monday.

One of those questions could involve what to do with the company's giant $726 billion cash horde. That's a lot of guacamole to have sitting on the books, especially now that the capital requirements are understood. Plus, banks have until 2019 to fully comply with the new requirements. This could mean activities such as dividend-paying could be restored.

Paying a dividend is important for financial companies like Citigroup. As a sign of the strength of “C” stock the company once returned a portion of its earnings to shareholders in the form of a dividend. That day could be dawning again, now that the Basel III accord has been reached.

As certainty has been achieved to a degree not reached previously, it's expect that company executives could now allocate capital more forcefully than they have since 2007.

Two goals that “C” needs to achieve to attract more investment money are achieving the stock price of $5 and to restore quartely dividends. That could help the company once again become 'investment grade,' which would bring in lots of large institutional investors who are currently avoiding the stock.

If that happens, current Citigroup stock investors will be very pleased.
